AIR INTAKE FOR AN AIRCRAFT TURBINE ENGINE
According to the invention, the air intake ( 2 ) is made of a piece ( 23 ) of fibre/resin composite material, reinforced on the side of the flange ( 24 ) by a reinforcing ring ( 26 ).
1 - 6 . (canceled)
7 . An aircraft turbine engine having a longitudinal axis (L-L) and comprising:
an air intake ( 2 ) provided with a tubular internal wall; and
a fan ( 3 ), supplied with air by said air intake and enclosed in a casing ( 11 ), which is likewise tubular, the rear end of said internal wall of the air intake and the front end of said fan casing being respectively provided with peripherally projecting collaborating connection flanges and joined together using first fasteners ( 16 ) such as screws, bolts or the like, which pass through said flanges and of which the axes ( 1 -i) are at least approximately parallel to said longitudinal axis (L-L) of the turbine engine, wherein:
said internal wall ( 23 ) of the air intake ( 2 ), including the connection flange ( 24 ) of said rear end ( 2 R), is formed of a component ( 22 ) made of a resin/fiber composite;
on the opposite side to the front end ( 11 A) of said casing ( 11 ), the peripherally projecting flange ( 24 ) of said rear end ( 2 R) is connected to said internal wall ( 23 ) by an at least approximately cavetto-shaped annular profile ( 25 );
a reinforcing ring ( 26 ) is attached to said rear end ( 2 R), said reinforcing ring espousing said at least approximately cavetto-shaped annular profile ( 25 ) and being secured to said rear end ( 2 R) by second fasteners ( 27 ) the axes (x-x) of which are at least approximately orthogonal to said longitudinal axis (L-L) of said turbine engine; and
said reinforcing ring ( 26 ) has said first fasteners ( 16 ) passing through it and is pressed against said collaborating flanges ( 15 , 24 ).
8 . A turbine engine according to claim 7 , wherein said composite is based on carbon fiber.
9 . A turbine engine according to claim 7 , wherein under said reinforcing ring ( 26 ), the thickness (E) of said component ( 22 ) made of composite is greater than in the tubular remainder of said internal wall ( 23 ).
10 . A turbine engine according to claim 7 , wherein said reinforcing ring ( 26 ) is made of metal.
11 . A turbine engine according to claim 10 , wherein said reinforcing ring ( 26 ) is made of titanium.
12 . A turbine engine according to claim 7 , wherein said second fasteners ( 27 ) are blind.
